APPARATUS FOR COOLING AND HEATING.

SEECIFICATION formingpart of Letters Patent No. 258,505, dated May 23, 1882, Application filed October 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOEL TIFFANY, a citizen of the UnitedStates, residing at Hinsdale, in the county of Du Page and State oflllinois, have invented certain new and useful Improvements in Apparatus for Cooling and Heating, of which the following is a specification, reference being bad therein to the accompanying drawing. 1

This invention relates to a new and improved apparatus which is especially designed for warming or for cooling and ventilating buildlugs, and which may also be used for heating, boiling, or evaporating water and other liquids, or for refrigerating purposes generally.

My invention consists in the combination of a steam reheater or superheater, a heat-radiator, a refrigerator, and a forcing-engine, all connected by means of pipes which are provided with cocks, and constructed as will be fully understood fromthe following description.

The annexed drawing illustiates in vertical section my improved apparatus.

The letter A designates a furnace of suitable construction, on which is mounted a steamreheater, A. This reheater is composed of any desired number of tubes, (0, arranged horizontally and communicating with vertical chambersB B, inclosed by boiler-metal plates. This reheater will in practice he iuclosed by furnace-walls for retaining the heat about its tubes and walls. The chamber B is provided with a pipe, 0, having a regulating and cutofi cock, b, applied to it, which pipe should communicate with a steam generator of any well-known kind. The common steam or vapor of water, at or above boilingpoint, is conducted through the pipe G into the chamber B of the superheater, the pipes at of which should be maintained at a high degree of heat forthe purpose of reheating the vapor and producing what is known as superheated steam. The highly-heated steam is conducted away from the chamber B of the superheater by means of a pipe, 0, which is provided with aregulating or cut-off cock, 0, and introduced into the chamber (1 of a radiator, D. This radiator consists of an outer shell of boiler-iron, two horizontal tube-sheets, and

any desired number of radiating tubes, e,

communicating at their lower ends with the chamber cl and at their upper ends with a similar chamber, d. The radiator may be providedwith branch pipes for conveying the steam to other radiators located in different apartments of abuildingfor warmingthe same, and it is also provided with an outlet-pipe for conducting off the water of condensation and affording acirculatio-n. Said branch and outlet pipes should be provided with regulating and cut-off cocks.

It is obvious that the radiator D may be used for boilingliquids-such, for instance, as

molasses, salt-water, &c.for the purpose of evaporation in the manufacture of sugar, and the production of salt. When used as an evaporator the radiator should be arranged in a suitable vessel, D, for containing the liquid to be acted on by the heat.

Gr designates a refrigerator, which communicates with the radiatorD by means ofa pipe, f, provided with a cock, 9. This refrigerator is composed of horizontal tubes it, connected to tube-sheets and surrounded by a shell of boiler-iron, like the superheater above described. One end of the refrigerator communicates by means of a pipe, p, with an air-engine, H, of suitable construction, which is designed for forcing air through the refrigerator, Where it is cooled, and thence forcing this cold air into and through the radiator D. It is of course understood that when this cooling process is conducted all communication between the radiator D and the superheater is cut off by simply turning the cock 0 in pipe I).

For the purpose of coolingthe air in its passage through the refrigerator G this apparatus may be surrounded and charged internally with ice or a compoundof ice andsalt, or when ice is scarce waterat the temperatureof springs may be circulated through and around the refrigerator outside of the tubes and. air-chambers thereof.

It will be seen from the above description that when the communication betweenthc refrigeratorand the radiator is cutoff and steam is forced through the latter it serves to radiate heat into the apartment in which is arranged.

It will also be seen that when the communition between the refrigerator and the radiator is opened and cold air is forced through the latter it will serve to reduce the temperature of the apartments.

The radiator may be located in apartments for preseving meats and other articles and the temperature therein reduced to any required degree by properly refrigerating the air, which will part with a large proportion of its moistuie while passing through the rel'rigerator.

I do not claim superheating stean'i, neither do I claim the use of hot-air tlues for conveying either hot or cold air.

Having described my invention, elaim- 1. The combination of a radiator, a steamsuperheater, a pipe directly connecting, the heater with the radiator,a refrigerator, a pipe directly connecting; the refrigerator and the radiator, stopeoeks in said pipes, an air-fore ing apparatus, and a pipe connecting said airforcing apparatus with the refrigerator, all substantially as described.

2. The combination of a tank, a radiator therein, a steam-heater, a pipe directly connecting the heater with the radiator, a rel'rigerator, a pipe directly connecting the refrigerator and the radiator, stop-cocks in said pipe, an air-forciugapparatus,and a pipe connecting said air-forcing apparatus with the refrigerator, all substantially as described.

JOEL TIFFANY.
